Jabon (Anthocephalus cadamba [Roxb] Miq.) is one type of tree that has a high prospect for industrial plantations and reforestation in Indonesia, due to its very fast growth and relatively easy silvicultural treatment. The growth of a plant is strongly influenced by photosynthesis. The process of photosynthesis can take place because of the presence of pigments called chlorophyll. The formation of chlorophyll is influenced by environmental factors. Therefore, studies have been carried out on the chlorophyll content of Jabon leaves in different locations. This research was conducted from March to May 2019. The samples came from the Sungai Nyalo, Pesisir Selatan, and Lubuk Alung, Padang Pariaman. While the chlorophyll content of Jabon leaves was tested at the Laboratory of Plant Physiology, Department of Biology, FMIPA UNP. This research is a descriptive study that was analyzed by the T test at a significant level of 5%. The results showed that there were differences in the chlorophyll content of Jabon leaves in the Sungai Nyalo, Pesisir Selatan with value 44,26 (mg/g) and Lubuk Alung, Padang Pariaman with value 19,45 (mg/g).

This research was aims to determine the response of jabon seed germination toward duration of combustion and light. This research was conducted from January to June 2018 at the Biology Laboratory and FMIPA UNP greenhouse. The design used was RAL with 2 factors. The first factor is the duration of combustion and the second factor is the light treatment. Based on the design obtained 10 treatment combinations and each treatment was repeated 3 times so that there are 30 units of experiment. Parameter observed is the number of seeds germination. The results showed that light treatment, combustion duration treatment, and interaction between combustion duration and light give good effect on the number of seeds germination. The seeds with the combustion treatment for 15 (A2) minutes had the highest number of sprouts that was 342.83 sprouts per 0.2 gram of jabon seeds. For light factor, many seeds germinate on the shelter treatment (B2) of 349.59 seeds per 0.2 gram of seed. While the combination of treatments showed that the best number of seeds germinated was in the combustion treatment 12.5 minutes with germination in the sheltered place (A1B2) that produced 564.67 sprouts per 0.2 gram of seed.

Jabon (Anthocephalus cadamba [Roxb] Miq.) Is a type of wood that is fast growing and has adaptability in various habitat types. Anatomical characteristics of wood are strongly influenced by environmental factors. This study looked at the dimensions of fiber and the derivative value of jabon wood fiber from the Sialang Dharmasraya and Tabing Padang regions. This research is a descriptive research. Observation of fiber dimensions using wood maceration techniques following the Forest Products Laboratory Method. The results showed that the value of wood fiber dimensions from the Sialang area was higher than those from the Tabing area. In Sialang it has wood fiber length of 603.82-1061.23µm, fiber diameter of 12.37-21.22µm, lumen diameter of 3.81-12.97µm, and wall thickness of 2.75-7.49µm. Whereas, in the Tabing area it has wood fiber length of 592.91-844.38µm, fiber diameter 11.80-20.35µm, lumen diameter 6.14-14.35m, and wall thickness of 1.91-4.54µm. The derivative value of jabon Tabing wood fiber is higher (runkel ratio 0.63-0.62, felting power 41.49-50.25, flexibility ratio 0.70-0.52, coefficient of rigidity 0.22-0.16 and mulsteph ratio 50.27-72.92%) compared to Sialang area (runkel ratio 1.15-1.44, felting power 50.01-48.81, flexibility ratio 0.61-0.30, coefficient of rigidity 0.35-0.22, and mulsteph ratio 62.64 to 90.51%). The quality value of jabon wood fiber at Tabing is better than Sialang. The results of this study can be used as information in jabon wood cultivation.
